Story Highlights

Shepard, 21, was wanted by Green Bay police for the April 15 shooting death of Steven M. Sims, 32, at 1144 Stuart St.

Court documents and police say Sims was shot after a confrontation at the Stuart Street address. Sims entered the home through a back door, was shot, and ran out of the house.

A witness who ran out of the house when the shooting happened said he saw Shepard pull a gun from his pants and heard three or four shots, according to the criminal complaint charging Shepard in the shooting.

Police said Shepard had been released from prison and arrived in Green Bay by bus from Kenosha on the day of the shooting. He pleaded guilty in 2010 to a substantial battery charge in Brown County, according to court records.

Sims had been living with his girlfriend on Stuart Street but moved out because of problems in the relationship. On the night of the shooting, Sims entered the apartment when Shepard, who also dated the woman, was inside. Sims and Shepard were "familiar with each other," police said.

Shepard was arrested by the Kenosha Police Department working in conjunction with the Racine Police Department. He was taken into custody without incident.

Green Bay police said they interviewed Shepard in Kenosha and are working on having him transferred to Brown County.

Police said no other information will be available over the weekend.
